Replacement 12-Pack of Pre-Filters for the FM-14 Commercial or Residential Smoke Eater for Solid Ceilings
The pre-filter is the first of 3 filter stages in the FM-14. Its function is to remove the larger particles so they don't clog the High Efficiency filter. This includes lint, hair, dust, etc. The easy-to-change pre-filter should be replaced, on average, at least once per month. This will ensure your smoke eater continues to function properly. Pre-filters CANNOT be washed.
Replace the FM-14 pre-filter every month.
